NY, OF BROOKLYN, NEVI YORK, CORFOEATION OF NEW YORK.

Application led June 10, 1907. Serial No. 373,098.

To all whom it may concern: y

Be it known that l, ADoLri-r PoTnnviN, a

citizen of the United States, residing in the borough of Brooklyn,county of Kings, city and State of New York, have invented certain newand useful improvements in Machines for Making Boxes, of which thefollowing is a specification.

' This invention relates to machines for making paper boxes; and moreespecially to that class of machines in and by'which previously cut andscored blanks are guinined and folded to constitute flat tubular bodieswith projecting end flaps, such bodies being adapted for subsequentmanipulation to form boxes or cartons in a manner well understood.

The present invent-ion, generally stated, concerns `various improvementsin the blank carrying vand folding mechanisms as will be hereinafterparticularly described and claimed.

In the annexed drawings t-he improvements are illustrated as embodied ina machinefor making dat carton tubes, but it is to be understood thatthe invention may be advantageously employed in the production of otherboxes, shucks and analogous articles. It is also to be understood thatthe form of embodiment of the invention herein set forth has beenselected for exemplitication purposes only, and that the apparatus maybe modified in many respects to meet varying requirements, withoutdeparting from the fair spirit of the invention.

Referring to the drawings-Figure l is av plan view of the machine. .Fig.2 is a side elevation thereof, partly in section. Fig. 3 is alongitudinal vertical section, as on the line 3 3 of Fig. l. Fig. 4 is atransverse vertical section, enlarged, as on the line 4-l of Fig. 3.Fig. 5 lis a plan-of the adjustable supporting frames for the blankcarrying and folding belts, one set of belts being omitte'd to exposeparts otherwise concealed. Fig. 6 is a side elevation of Fig. 5, part ofthe frame wall being broken away;

20 designates a supporting frame of suitable shape and size for itsintended purpose, and 21 the main driving shaft journaled therein andadapted to be actuated from a convenient source of power.

22 indicates the usual parallel feed-rollers to the bite of which theforward edges of the Specification of Letters Patent.

"ME-CHINE FOR MAKNG BOXES.

l individual box blanks (A) areidelivered,

and the blanks thereby successively fed into the machine. The shafts ofthese rollers are journaled in boxes in the sides of the main frame, andare provided at or near their respective ends with interineshing gearwheels 23. rlhe gear wheel of thev lower shaft meshes with an underlyingpinion 24 on a rammen nay ie, lair.

stud shaft, and this lpinion, in turn, is engaged with and driven by a.spur wheel 25 on a shaft 26 which extends transversely of the machineand in parallelism with the feed rollers. On the wheel 25 is abevelpgear 27 which meshes with a bevel wheel 23 on the forward end-oflongitudinally disposed shaft 29 journaled in suitable bearings onthemain frame. 0n the rearward end of the shaft 29 is a bevel wheel 30which -gears with a similar wheel 3l on a shaft 32adjacent to andparallel with the main shaft. The shaft 32 carries at one end a gearwheel 33 which meshes with a similar wheel 3l on the main shaft. Thusthe power is transmitted from the main shaft to tlieshaft 26, and thencethrough the intermediate gears to t-lie feed-rollers. These rollersdeliver the blanks to two carrying belts 33 extendinglongitudinallyofthe machine, which belts are adjustable in parallelismtoward and from each other as the width of the blanks may require,suitably-disposed supporting carriages therefor being provided, as willpresently appear. ered tothe carrying belts 83, the marginal As theblanks are deliv edges (a) of the blanks are progressively supplied withliquidl glue, or other suitable cementing medium, by contact with thepe- 7 riphery of a glue-applying wheel 84, on the driven shaft 26. Thiswheel contacts pe Awith the pinion 25 on the driven shaft 26.

A grooved roller 90, whosesshaft'is journaled in a bracket 91 projectingfrom the loo suitably disposed frame bar maintains the marginal edges ofthe blanks in Contact with the glue-applying wheel. (Figs. 1, 2 and 4.)

Each of the carriages for the blank carry- .l ing belts comprises a pairof spaced parallel bars 92 in and between which are journaled which aremounted to slide along the transversedriven shafts 26, 32,-respectively, previously described. The belt passes around these pulleys911, 95, and is impelled thereby.

' It also passes upon guide pulleys 90, whose shafts are mounted inbrackets 97 depending from the bars 92. An idler pulley 98 rests uponthe belt at a point intermediate the guide pulleys so as tokeep the belttaut, the idler being conveniently carried by an arm 99 which is free-to turn on, and move longitudinally of, a transverse shaft 100supported in the sides of the main frame. (See Figs. 2 and 3.)

The carriage bars 92 are provided near their respective ends -withbrackets 101 through apertures in which freely extend transverse guidingand steadying rods 102. These -brackets are also provided with threadedapertures for the reception of correspondingly threaded screwV shafts103 whichl roject outwardly beyond lthe adjacent si e of the main frame,0n the projecting ends of the shafts are sprocket wheels 104: aroundwhich passes an endless chain 105 whereby when one of the shafts 103 is,properly rotated both shafts will be correspondingly actuated to cifectthe bodily adjustment of the carriage and its appurtenances toward orfrom the longitudinal median line of the machine, as desired.

One of the shafts is provided with a hand wheel 106 to facilitatejt-heoperation just described.

It is to be understood that the two carriages are identical inconstruction and operation, saving that they are oppositely dis'- posed,and that they are each provided with corresponding adjusting devices ofvthe character described, whereby they may bel independently adjustedfrom or toward each other, as occasion may require.

Rising from each of the brackets 101,

preferably integral therewith, is an arm 107 which curves outwardly andinwardly to overhang the adjacent carriage, or n'early so. On this armis bolted a bar 103 which extends longitudinally of the carriage. At

the respective ends of this bar are depending apertured bosses 109 inwhich are slidingly fitted vertically movable posts 110 rising from abar 111 which extends directly aboveand parallel with the carrying belt.In the bar 111 are journaled a series of close-lyingrollers 112 whichare held yieldingly in contact with the belt by suitable' springs 113contained in the apertures of the bosses 109. from the lower portion ofthe bar and constituting, in eHect, a continuation thereof, is a flatstrip 109a which is about the width of the belt and is adapted to lieparallel Extending rearwardly thereto, or substantially so, in a mannerto present a straight supporting edge to the blank as the lat-ter isbeing bent and folded, as hereinafter described.

By the construction just described it will be -seen that the rollers 112and their supporting devices togetherwith the edge strips 10921 areborne by the carriage and are'adjusted concurrently with thecarryingbelt. It will also be seen that as the blanks are fed to thecarrying belt they are maintained in close contact with the belt by theseries of over-hanging rollers so as to be effectually transported. l

Adjacent cach of the carrying belts, and traveling concurrentlytherewith, is a twist ed folding belt 114 which is constructed andvarranged to engage the opposing edges of the blanks before they leavethe pressure `the blank and `insure the close contact of the guminedmargin with the underlying side portion of the blank. The belt 114passes' around a slightly inclined pulley 115, the shaft of which ismounted in a bracket 116 bolted to the outer side of the carriageadjacent the depending bracket 97, and also around a pulley 117 mounteddirectly above the pulley 95 which supports the rearward portion of thecarrying belt. The pulley 117 is slidingly mounted on a shaft 118 whichextends transversely lof the mainframe and in parallelism with the shaft32 of the lower pulley 95. The shaft 118 vis provided with a -gear wheel118 which corresponds and meshes with the gear wheel 33 on the shaft 32,thereby effecting the concurrent travel of the folding and carryingbelts. The car-v riage is provided with arms or jaws 119 which embrace aperipherally grooved hub of the pulley 117 so that the latter willpartake of the adjustments ofA the carriage. The belt 114 is crossed` inits passage from the lateral pulley 115 to the overlying pulley 117, andappropriate uide devices are providedto give the requisite twist orangle to the belt as it passes to, over upon, and along with, thecarrying belt; In the present instance, a vertically disposed guideroller 120 is arranged in rear of the pulley 115 so as to direct tovertical position the portion of the belt contacting therewith. Thisroller is mounted on a stud rising from a bracket 121 bolted to theouter side of the carriage. In the rear oftheY roller is an inclined bar122 which extends in an oblique path over the carrying belt, and servesa back support and guide for the folding belt 11st as it pass from -theroller. This.

bar 122 is alhxed to a bracket 123 which is adjustably secured byset-screws 124 to a supporting rod 125 extending longitudinally of thecarriage and near to the rearward end thereof. The rod is secured tobrackets 126 bolted on the side ofthe carriage. Slid- 'ingly fitted. tothe rod are inwardly extendare adjustably secured to the rod 125 by setscrews 129, and hence by releasing and setting lthe rollers atpredetermined positions along the rod, -and also by adjusting the'bar122 along the rod, the angularity -of the folding belt may be nicelyregulated to insure the eflicient folding of blanks of Various stylesand sizes.

From t-he foregoing it will lbe seen that the folding beltand itsappurtenances are mounted on the carriage, and are thereby bodilyadjusted correspondingly with the carrying belt and its connections.

As the folded and cemented blanksor flat tubes as they may betermedapproach the rearward 'or delivery end of the machine, they arefirmly clamped in horizontalposition by the opposing horizontal portionsofthe two belts, thereby insuring the ef- Y cient union of the foldededges of the blanks.
